Site Based Management Plan
Fauna and Flora
Any necessary vegetation and fauna protection measures shall be in place prior to the commencement of any stage of
Site excavations and be maintained until the area is fully rehabilitated, and shall include:
- Installation of markers, flagging or fencing around protected vegetation/vegetation to be retained zones or areas
under rehabilitation; and
- Implementation of stormwater, erosion and sediment controls before any excavation works commence for each
stage of extraction and are maintained until the area is fully rehabilitated.
Vegetation Clearing
Prior to the clearing of any vegetation, a Vegetation Clearing Plan shall be prepared in accordance with the following
protocols:
- land disturbance is to be minimised and clearing limited, as far as practical, to the extent necessary for each
stage;
- the sequence and direction of vegetation clearing will be designed to ensure fauna has sufficient opportunity to
move from the clearing Site without human intervention;
- vegetation clearing shall be carried out in stages using a sequential clearing technique; and
- prior to clearing, the limits of the approved area to be cleared shall be clearly marked with markers, flagging or
fencing prior to clearing.
Topsoil Management
Topsoil is the material that supports and promotes plant growth, soil micro-organisms, organic matter and nutrients.
Topsoil is defined as the organic-rich and friable layer beneath the natural ground surface. The physical properties of
topsoil are also important for promoting and supporting plant growth.
The following measures should be implemented for topsoil stripping:
- topsoil should not be stripped when it is too wet or too dry;
- topsoil when stripped, should be used directly for rehabilitation to the maximum practicable extent or stockpiled
and preserved for no longer than 12 months;
- topsoil stockpiles are not to exceed a height of 2 m, shaped (i.e. batters no greater than 1H:2V) and revegetated
to protect the soil from erosion and weed infestation;
- maintain stockpiles in a free draining condition and avoid long-term soil saturation;
- “run on” water should be prevented from flowing across the area to be stripped; and
- topsoil stripping should be limited to the minimum area necessary.
The following measures should be implemented for topsoil spreading:
- whenever possible, stripped topsoil should be directly placed on an area undergoing rehabilitation;
- areas to be topsoiled should be re-shaped prior to placing topsoil;
- equipment used to spread topsoil should be scheduled to avoid compaction;
- before respreading the topsoil, loosen the subsoil to break up any compacted or surface sealing and to enable
keying of the two soils;
- on slopes less than 3:1 (H:V) loosen lightly compacted subsoil with a tined implement to a depth of 50 mm to
100 mm, and heavily compacted subsoils to a minimum depth of 300 mm, ensuring all ripping operations occur
along the contour;
- topsoil to be removed from stockpiles in a manner that avoids vehicles travelling over the stockpiles;
- topsoil to be re-spread in the reverse sequence to its removal so that the original upper soil layer is returned to
the surface to re-establish the entrapped seed content of the soil;
- ensure all exposed subsoils are covered;
- topsoil be respread over selected batters, contours, bunds and disturbed areas to a minimum thickness of
100 mm;
- after spreading topsoil, ensure the surface is left in a roughened state to assist moisture infiltration and inhibit soil
erosion;
- prior to any planting, cultivate any compacted or crusted topsoil surfaces (to a depth of 100 mm, but no greater
than the depth of the topsoil);
- soil spreading is to be immediately followed by seeding or planting if applicable; and
